2020-01-23clk: zynqmp: Warn user if clock user are more than allowedRajan Vaja
Warn user if clock is used by more than allowed devices. This check is done by firmware and returns respective error code. Upon receiving error code for excessive user, warn user for the same. This change is done to restrict VPLL use count. It is assumed that VPLL is used by one user only.
